The phrase-change 🔑 alert never fired live because the deployed artifact
didn't contain it — functions/dist is committed and is what deploys, and I
changed functions/src without rebuilding it. My own gates were green and
irrelevant: tsc --noEmit emits nothing, ts-jest compiles in memory. The user
deployed twice, faithfully, and shipped my stale artifact both times. "git
status clean" is not "deployable current".
Two fixes: dist rebuilt (diff confirms exactly one stale function,
onCoupleKeyRotated — the phrase edge), and firebase.json now carries a
predeploy hook (npm run build) so every functions deploy compiles first —
the mistake class is structurally gone rather than remembered. Landmine
written up as FUNCTIONS-DIST-STALE in the manual: when verifying "is X
deployed", compare against dist/, not src/ — src is the intent, dist is
the truth.
Functions tests green (108).
